2. Children and pregnant women: Children and pregnant women are special groups, so it is necessary to appropriately increase the intake of milk to meet the body's demand for calcium and protein. Ordinary children can drink 500~800 ml of milk every day, and pregnant women can drink about 500~ 1000 ml of pure milk.

Milk is rich in calcium. Protein can promote the repair of the body, and can also supplement enough calcium to reduce the incidence of osteoporosis. When choosing milk, pay attention to choosing pure milk or fresh milk, because the disinfection shelf life of fresh milk is short, so drink it as soon as possible after purchase. If lactose is intolerant, you can choose Shuhua milk or yogurt, which can reduce gastrointestinal reaction. Besides, avoid drinking milk on an empty stomach. Drinking milk on an empty stomach will stimulate gastric mucosa to produce more gastric acid, causing abdominal distension, diarrhea, abdominal pain and other discomfort.
